Hello everyone. I am new to this post. Just recently purchased a 2004Audi A8 about a month ago.
I'm here because I have a question that someone may be able to answer. I've noticed over the past couple of days that the temperature handtends to drift near the H (Hot), as if the car is running hot. Then, when I'm idle it will go back to the middle.

Is this normal? If not, does anyone have a clue to what may be going on. Also, when I'm parked, the car sounds like it's running pretty loud.
